any suggestions on this Beast-warrior Koaki meiru deck?

You should probably put some odds and ends into your deck like penguin soldier, coz the boost your deck power and don't make your deck all beast.

I have a wind deck and there are cards that are just anti-wind so they completely bring down my plan. Also, a weakness in your deck is that it uses a lot of good monsters, but that you use the same monster a lot of times, so if you duel someone who knows your deck or seen through your cards and uses something like Cloak and Dagger, it will bring down your deck power, not to mention you don't ahve a lot of spell destruction cards.

in case you base a deck around those enjoying cards then you certainly extra efficient have a consistant build with 3 iron cores. The monsters are effectual yet you'll want those iron cores to maintain them out or they die. maximum individuals basically use a pair of them for categories of decks as ingredient decks for thier consequences. Like some human beings throw jujitsu masters and the guardians into the ingredient decks so as that they might save the guardians out basically via revealing a rock monster rather of teching iron cores...do what you think of could be relaxing or cool xp.

Where's sand man and guardian they are good in any koaki deck. 3 magical hats is dumb with iron transport get rid of them. Ok the guy below me is completely ridiculous but if you want to tech card try Juijitsu master and stun cards like rai oh doomcailiber knight and oppression. Mirror force is needed. Also where is iron core luster thats one of their strongest traps. Consider Core compression for draw power and a boss monster like valafar, maximus, rooklord comboed with doom, drago, and bergazak respectively.
